It took me five days to compile this list but here is a guide to the lowest same week combined positions for each top 40 sales position since streaming came to the fore. Songs marked in green indicate it's peak position.

Sales position * lowest overall position in same week * Performer * Song * Date

Taylor Swift gets the awards in most categories - I see this as a good thing, enormously popular, sells consistently well, and doesn't care a fig about streaming or chart positions resulting from streaming. Hooray for Taylor Swift!

Just a week after the first top 5 sales entry not to be overall top 10 we get another and it also breaks the record for lowest position for that sales bracketBlank Space breaks the record for lowest overall position as a top 30 sales entrant and while Shake It Off happily loses one negative posiiton record it breaks another!
